[Q] Nexus 7 Failed ROM Flash Help!

I have CWM 6.0.1.0 on my nexus 7. I was rooted but running the stock ROM. I wanted to flash CM10. I booted into recovery, wiped cache, dalvik, and factory reset. I then flashed the .zip file. When I rebooted the device it never got out of the CM boot screen. That circle just kept spinning. I tried the toolkit but the drivers aren't really working on my computer (crappy old XP laptop). I have formatted the system and SD card out of desperation which was honestly a stupid thing to do. So, where I am at now. I have no way to boot into android. Everything is wiped and formatted. Toolkit, adb, nor fastboot will work. I thought fastboot would save me but I can't get it work. Not even on my wife's mac. So what are my options? Please let me know if there is something important I am leaving out.

It can take a while to get a new rom up and running. How much time did you give CM to install before you interrupted it?

I let it go for at least 30 minutes. I finally got adb to push a ROM to the device. Problem solved. Thanks though.

maybe it was a bad download?

It can stand a spell to get a new rom up and jetting. How some instant did you utilize CM to install before you broken it?

Thats possible. I tried re-flashing it numerous times but they all got stuck in boot. I am now up and running with SmoothROM. I might have to re-download CM10 sometime and try again.

Hey guys I now has a similar problem. I flashed a bad copy of my Rom and when it failed to boot I too wiped everything in desperation. I know I'm an idiot! Now I need to push both a Rom an kernal to my root directory but I'm not clear on how to install my kernal. Once I push my Rom I can use my recovery to install the Rom. But how do I install the kernel? I'm using cleanrom which comes zipped with the kernal. I can't fastboot flash it because I cannot turn on USB debugging. Gary

To use fastboot you don't need to have switched on USB debugging, it's sufficient to go to bootloader mode and connect your PC to it.
(If you have already installed the correct drivers on your PC.)

PLEASE HELP. Boot loops to recovery

I installed the HORSEMAGEDDON ROM and it worked - for the most part. But it kept giving me annoying errors about different apps that were attempting to update every time I turned it on. So I tried to restore my backup that I had made with CWM 6.0.2.8. However the backup apparently did not restore properly because it now boot loops back into CWM any time I try to start it. I get the errors:
E:Can't open cache/recovery/log
E:Can't open cache/recovery/log
E:Can't open cache/recovery/last_log
E:Can't open cache/recovery/last_log
So I tried to reflash HORSEMAGEDDON but it still loops back into the CWM recovery screen.
I have wiped everything according to the instructions on the HORSEMAGEDDON thread.
HELP!! This happened to me on another U8800-51 phone and I wound up hard bricking it trying to get back to stock.

Anybody???
Does anybody have any ideas on how I can fix this?

Did you wipe cache/dalvik cache?

Yes. I did a wipe of data and factory reset as well.

What I would do is get an SD card with a custom rom on it and try installing it from recovery menu

Obviously you have been having problems with that rom, so go with something different.

Okay. Here is what I did step by step:
1. I was on Stock 2.2.2 Froyo and flashed HORSEMAGEDDON successfully. But I had some errors related to updates since it was such an old ROM the updates were all for much newer versions of the apps tied to 4.x.x.
2. I attempted to restore my backup made with CWM 6 to return to the stock. It said it completed successfully but when I rebooted it just looped into the recovery screen with the error messages posted in my first post.
3. So I tried to reflash HORSEMAGEDDON and it said it completed successfully. But it still bootloops into recovery.
4. I can access most of the features of the recovery. I can access the pink screen and swap recovery versions. I can access my SD card from my PC when I mount it from recovery.
5. Yes, I did do full wipes with each attempt to reflash.
The ROM was not the problem. It worked and worked well other than update issues for apps. It was only after attempting to restore to stock I ran into issues.
The problem appears to be something was corrupted when I tried to restore my backup, even though it said it completed successfully.
So if I try to flash yet another custom ROM, even if I could find one I trust given all of the version issues etc., I don't think it would act any differently. But if somebody can recommend one I am all ears. Keep in mind I have a -51 phone so it will have to be for that or the PRO.
Given that, how can I get back to stock? Am I the only person who has ever had this problem? I don't believe that is the case, so somebody must know how to fix it or can point me to a procedure to repair the internal memory.
Help!!

I'm new at xda so it's not letting me post an external link. Google "bootlooping" and the first one in list is from xda, just follow the instructions

None of the fixes on this link seem to apply to my situation.
When I said "bootloop" I may have misused the term. What happens is I power up, it goes to logo screen for about 10 seconds, shuts down and restarts to logo screen then goes into recovery after about 5 seconds. From other info that I have found it is due to a corrupt bootloader and I need to reflash the bootloader. Problem is, reflashing the bootloader i.e. CWM, does no good at all.
I am also hampered by lack of info specific to the -51 model. And I cannot find a copy of the stock ROM anywhere that is for the -51.
So essentially I am screwed. All of that said, I have found a new phone for $40.00 so all is not lost. It's a U8800 but not the -51 or PRO. I don't plan on customizing it, I'll just stick with stock. After trashing two phones even after following the advice to "BACKUP" I think enough is enough. Backing up did me no good whatsoever in both cases.
In my estimation, the culprit is CWM, or at least the versions I used.
If anybody has any advice I'm all ears.

now it's the original recovery, not twrp.it seems like ……i did wipe my internal data………………i forgot to backup…………what can do do

So your phone will boot but turns off.
You need to root install custom recovery and you could reflash one of the stock rooted roms.
You also could try to lg flasher and flash stock but must get into download mode.

D802 stuck in recovery in a weird way

Hi guys, I made a mess today. I decided to restore my stock LG software backup and everything went well. Then there were some LG updates and when they downloaded, I chose to install them. That took me to TWRP. I figured it needs the stock recovery to install the updates so I gave up on the updates and tried to reboot my device. It booted back to TWRP. I found it a bit weird, but I didn't care since I had a backup on the phone. I wiped data, cache, system and dalvik and restored the backup. Guess what, the phone would still only boot into recovery. I started freaking out so I wiped everything except internal again and flashed an AOSP based rom along with the gapps. Still wouldn't boot except recovery. Then I started to freak out even more and decided to wipe EVERYTHING, along with Internal storage. And here I am now, wiped every single thing on the device, stuck in recovery and can't connect my phone to the PC with usb. just a few minutes before I have to leave home. Any ideas on how to fix this? It was just some pointless LG update and it caused such a mess... ADB sideload won't work for me, I'm gonna attempt to find some drivers or something.

Anybody?

Dude, I've done my research and tried to fix it myself. The phone won't go into download mode and it won't connect to my PC. Drivers installed, LG tool installed. I just don't know what to do and I need help from someone who does know.

If you have twrp 2.6.3.4 you sideload rom but this may not help you.
You are going to have to go back to 100%stock.

In TWRP you have USB-OTG. If you have this cable you can install ROM from USB-flash)

I had the same issue. Only way to fix it was with the LG flashing tool. Make sure the usb port you are using on your computer is working and the cable isn't broken. I just followed the steps from this thread and it worked 100% for me.

HELP!!!!

Not sure exactly what I did but I had installed a stock rom and while using the rom I got a software update. I tried to install the update and it said phone will reboot so I rebooted it. It took me to my recovery (Philz Touch recovery) then I attempted to reboot my phone but now it just keeps going back to recovery and wont go any further. I've tried to install another rom but it still goes right back to recovery after I reboot. Please someone help me out here. I'm pretty I'm not bricked but cant figure out what to do to get to my phone. I'm thinking I need to restore my phone back to factory and start again.

Hello, if you made a backup of your previous Rom, you don't have to do a factory reset, if you didn't make a backup in recovery mode, you can factory reset.[emoji4][emoji4]

Rule #1. NEVER INSTALL OTA UPDATES IF YOURE ROOTED!

Just saw your other thread. If you are not confident using adb just get yourself an otg cable, put twrp on a memory stick, mount the otg in philz and flash twrp from the memory stick. You can then use the terminal in twrp.
PS. A micro usb drive would work just as well.
